Abstract
Ausrichtung eines optischen Codierers im Hinblick auf ein Coderad. Eine Ausrichtungsvorrichtung wird verwendet, um den Codierer im Hinblick auf die Coderadfwelle auszurichten, durch Zusammenpassen mit der Coderadwelle und mit Referenzmerkmalen an dem Codierer, die Stifte oder Aufnahmeeinrichtungen für Stifte aufweisen können. Einer oder mehrere der Stifte können verjüngt sein, um eine Anordnung zu beschleunigen.Alignment of an optical encoder with respect to a code wheel. An alignment device is used to align the encoder with respect to the code adder wave by matching with the code wheel wave and with reference features on the encoder, which may include pins or receptacles for pins. One or more of the pins may be tapered to accelerate an assembly.
Description
Ausführungsbeispiele gemäß der Erfindung beziehen sich allgemein auf optische Codierer und insbesondere auf optische Drehcodierer. Weiter noch beziehen sich Ausführungsbeispiele gemäß der Erfindung auf eine Ausrichtung von optischen Codierern im Hinblick auf Coderäder.embodiments according to the invention general optical encoders, and in particular optical Rotary encoder. Still further embodiments according to the invention relate to an alignment of optical encoders with respect to code wheels.
Ein Codierer ist ein Bewegungsdetektor, der eine Rückkopplung zu einem Motorsteuerungssystem liefert. Ein typischer Codiererentwurf besteht aus einem Emitter-/Detektor-Modul, das in einer übertragenden, reflektierenden oder Bilderzeugungs-Konfiguration arbeitet. Wenn er in Verbindung mit einem Coderad betrieben wird, übersetzt der Codierer eine Drehbewegung und eine digitale Ausgabe.One Encoder is a motion detector that provides feedback to an engine control system supplies. A typical encoder design consists of an emitter / detector module, that in a transmitting, reflective or imaging configuration works. If he is operated in conjunction with a code wheel, translated the encoder a rotary motion and a digital output.
Wenn sich die Auflösung des Detektors erhöht, tun dies auch die Anforderungen nach einer ordnungsgemäßen Ausrichtung des Codierers im Hinblick auf das Coderad.If the resolution of the detector increases, so do the requirements for proper alignment of the encoder with respect to the code wheel.
Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Ausrichten eines optischen Codierers mit einem Coderad mit verbesserten Charakteristika zu schaffen.It It is the object of the present invention to provide a method for aligning an optical encoder having a code wheel with improved characteristics to accomplish.
Diese Aufgabe wird durch ein Verfahren gemäß Anspruch 1 und Anspruch 6 gelöst.These The object is achieved by a method according to claim 1 and claim 6 solved.
Gemäß der Erfindung wird ein optischer Codierer geschaffen, der zur Verwendung mit einer Ausrichtungsvorrichtung angepasst ist. Die Ausrichtungsvorrichtung passt mit der Welle zusammen, die das Coderad hält. Die Ausrichtungsvorrichtung weist Referenzmerkmale auf, die mit den Anpassungsmerkmalen in dem optischen Codierer zusammenpassen, wodurch eine ord nungsgemäße radiale und tangentiale Ausrichtung des Codierers im Hinblick auf die Coderadwelle bereitgestellt wird.According to the invention an optical encoder is provided which is suitable for use with a Aligned alignment device. The alignment device Mates with the shaft holding the code wheel. The alignment device has reference features associated with the fitting features in the match optical encoder, whereby a proper radial radial and tangential alignment of the encoder with respect to the code wheel wave provided.
